In the simulation, the base stations (BS) are set at 4 m above the ground, working as small-cell lamppost BS (the same as measurements [1]}). The carrier frequency \(f_c\)  is at 142 GHz with 1 GHz null-to-null bandwidth, since 1 GHz to a few GHz bandwidths will be used for future sub-THz and THz communications [2]}, [3]}. The user equipment (UEs) are set at 1.5 m above the ground with 15 dBi gain antennas and a 7 dB noise figure, as shown in Table REF .
